I'm am in the process do replacing my existing navnet 1 with a navnet 3d. I have a stand alone furuno 582l sounder and was wondering if it is worth it to upgrade to a dff1 black box? Is the increase in output power worth it? I fish inshore wrecks and reefs in about 75' to 150' and the offshore canyons here in NJ. Any thoughts would be appreciated.

What transducer do you have connected to your 582l? The DFF1 can be set for 600w or 1Kw. If you have a 600w and set the DFF1 to 1Kw it won't work for long.

Even tho I have seen many well placed 600s outperform a badly placed 1 KW. and remember not all 1 KWs are the same. elements count! Those new round flush ducers that can even do angles do not have as many elements as a normal bronze ducer has.

I was planning on installing a new 1kw thru-hull transducer. I can't recall exactly what model 600kw transducer I installed back in 2003, although I know it is a thru hull flush style with temp.

It is certainly worth upgrading to the DFF1 as it is a superior sonar to your curent unit. Far better filtering and it is full digital unit.
And having it integrated into your Navnet 3D system will be a positive also.

Also, if you use a 1 kw transducer, even at 600 watts, the increased sensitivity will pay dividends.

If you are looking at a thru hull the B164 is a 3 element transducer and is worth looking into.
At your depths cone angle is a consideration that is very important.

Are the new Airmar CHIRP transducers compatible with the GSD22?
For some reason I only pick up bottom and nothing in between. And have never been able to pick up bottom deeper than about 500ft. I am pretty sure I have a B60.
What would you recommend for mostly bottom fishing?

You can use a CHIRP transducer with a GSD-22 but I would not recommend it.
Too costly and you would loose a great deal of sensitivity on the 50 kHZ side.

So yes, you can use it..but no, it is not advised.

Second question:

I would recommend aTm260 or a M260 for fishing bottom at your depths....they are 50 times more sensitive than the B60 and then you also can use a full 1kw of power.
These two units are my number selling transducers for your fishing conditions and sonar type.

You will then be able to get the most out of your system.

PM sent.
